What a fabulous speaker. Similar sound to my C5 but obviously a little smaller in presence – all the frequencies are still there and well balanced though. A big plus is the battery is easily changed should a new one ever be needed – this is the only device I have seen which allows this. The only inconvenience is that when it auto switches off after a period of inactivity, unlike the mains powered C5, it has to be manually switched on and then has to reconnect to the network. Presumably this is to conserve battery power.
Super sound for size in a portable unit – perfect for outdoor space
great little box of noise
Small package- huge sound! Really, did not expect this deep bass at low volume. Excellent job, Audio pro.
